Terminal



March 9, 1937. G. k. PEIRSON I JERMINAL Filed July 19, 1934 Patented Man-9, 1937 UNITED STATES PATENT OFFICE George 1:. Pelrson, maria Rana. Application July 19,1934, N ssau: roam. (cl. 173-459) This invention relates to terminals for storage batteries and has for its object the provision of a simple device whereby corrosion around the battery post will be prevented. The invention is illustrated in the accompanying drawing and consists in certain novel features which will be hereinafter first iully described and then particularly defined in the appended claim.

In the drawing:

[0 Figure 1 is a plan view, partly in section, oi a.

terminal embodying the invention.

Figure 2 is an edge elevation'ot the same.-

Figure 3 is a perspective view showing the absorbent washer removed from the clamp but approximately in its proper relation thereto.

A battery is indicated by dotted lines at I and a battery post is likewise indicated at 2. A cable is indicated at! and it will be observed that the insulating. covering of the cable is removed at one end so that said end of the cable, as shown at 4, may be fitted tightly in a sleeve .5 formed on one side oi the clamp l which is intended to encircle the battery post. At the side opposite the sleeve, the clamp is split and formed with mating lugs I through which-a scouring bolt! is inserted, said bolt being-equipped with a nut 0 adapted to be turned home against the adjacent lug and thereby firmly secure the clamp around the battery post. In carrying out the present 7 invention, pinsor studs III are embedded in the lower edge or the clamp so as. to depend therefrom and these pins or studs are driven through a washer Ii oi wool ielt, the ends or the pins or studs being upset against the bottom or the washer, as shown at l2.

The clamp is secured around the battery post in the usual manner, as is obviouiuand the washer will beinterposed between the clamp and the top of the battery casing, as shown in 2 .40 and as-will be understood. Thewasher is impregnated with oil or similar material which will I the washer in place.

lubricate the post and'will resist corrosion so that when .it is necessary to disconnect the cable, breaking or the parts will be avoided and-the terminal may be very easily removed. It is'well' known that, due to the leakage or acids from the corrosion occurs around the battery post and around the top or the battery case and various eflorts have been made to overcome this dihilculty: The provision or a wool ieit washer im- -pregriated with oil and interposed between the clamp and the battery will prevent corrosion and will add only a trifling expense to the ordinary cost of the battery. In the present instance, the washer is tired to the underside oi the clamp so that it will always be in placeand cannot be lost when the clamp is removed from the battery to facilitate renewals or repairs. The washer will have no deleterious eilect on either the post or the battery, and'by occasionally applying a few drops or oil, the proper condition ofthe washer will be maintained for along period.

Having thus described the invention, 1- claim:

A terminal -comprising a clamp having a post encircling portion, means for contracting the post encircling portion to bind the same about a battery post, and pins embedded in the under face of the post encircling portion of the clamp in spaced relation to each other circuinierentially thereof and depending therefrom, and a washer or absorbent material bearing against the under face or said clamp for disposition between the clamp and the upper surface of a battery to prevent access or corrosive material tothe. clamp,

said pins being 0! greater length then the thickness 0: ma washer and extending throu'ghthe 3 washer and having their lower tree end portions initially projecting from .the washer and bent upwardly and clinched against the under iace oi the washer and embedded in the washer to hold GEORGE E.
